Method Detail

set

public void set(int x,
                int y,
                Color color)

set

public void set(int x,
                int y,
                int pixel)

public void set_red(int x,
                    int y,
                    int r)

get_red

public int get_red(int x,
                   int y)

set_green

public void set_green(int x,
                      int y,
                      int g)

public void set_blue(int x,
                     int y,
                     int b)

get_blue

public int get_blue(int x,
                    int y)

set

public void set(int x,
                int y,

                int b)

set_data

public void set_data(int[] image_data)

Puts the image data into this image. This data must be in the same format as specified in this image.

Parameters:

image_data - the data to set

set_data_element

public void set_data_element(int index,
                             byte val)

Sets a data element in the ZPixmap directly. This manipulates the underlying data directly. It is recommended to use one of the other accessor methods instead.

Parameters:

index - the index of the data element to set

val - the value

get_data_element

public byte get_data_element(int index)

Returns the data element at the specified index. This manipulates the underlying data directly. It is recommended to use one of the other accessor methods instead.

Parameters:

index - the index of the data element

Returns:

the data element at the specified index

get_data_length

public int get_data_length()

Returns the length of the underlying data array.

Returns:

the length of the underlying data array
